Being beautiful is one of the chief features of social stratification. We all find ourselves ranked according to a variety of dimensions and sometimes even from our parents. There are some motivational and driving forces, physically, morally that hinders a strong deep or close association or acquaintance between two or more people that may range in duration from brief to enduring this association may be based on inference, love, solidarity, interaction or some social commitment. In other words we seek out some people and actively avoid others. A lot of social scientists have worked and collected an impressive body of research on interpersonal attraction with the focus on appearances. How a person looks is very important in the early stages of a relationship.
It is amazing that beauty is such an impactful factor of every person's life. From school grades to getting the job that you want, beauty can sometimes come between you and your goals if you are not considered beautiful. It is said that there is a halo effect where people assume that because a person is beautiful in their eyes, that person must be trustworthy, sociable, sensitive, and interesting. Partnered up with the halo is also the horns effect. This is an assumption that less beautiful people are mean, sneaky, dishonest, and antisocial. Most people would respond to this topic by saying that they would never make such a crazy assumption about any person just because of their looks. They would be wrong because it has been proven in many studies that this judgment happens automatically.
The fact that physical attractiveness or lack of it affects or determines certain aspects of our lives be it at work, school, or environment leads to a lot of research into person's perception and esoteric branch of psychology. In general, all of the factors that determine or influence the dynamics of interpersonal relationships and choice of relational partner all relate to being beautiful or physical attractiveness.
